FELLY-TIGHTENER.

SPECIFICATION forming part of Letters Patent No. 270,413, dated January9, 1883.

Application filed May 2, 1882.

.act descriptioni The object of myinvention is to provide means fortightening or taking up the play in fellies of wheels in cases where itis not convenient or desirable to do so by having the tire reset.

My invention consists in a novel construction, arrangement, andcombination of a rightan d-left-threaded screw, two internally-threadedbars, two pairs of clamping-jaws, and two pairs of lastening-bars,together with certain details connected therewith, whereby provision ismadefortighteningiellies, eitherby drawing or pushing, without removingthe tire, and, if necessary, without removing the load which 'may beupon a wagon, as hereinafter more particularly described.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view of my invention in position for use. Fig. 2 is alongitudinal sectional view. Figs. 3, 4, and oaredetail views.

A reprcsentsaright-and-lettthreaded screw with an angular head, a,midway of its length.

B B are two bars, which are provided respectively with righthand andleft hand threads. The bars may be of iron and have the threads formedin them, or they may be of wood simply bored and provided with straps DD,-embracing two or more sides, and having the threads formed in theportions which are at the inner ends of the bars, or may be made of anysuitable form or material.

E represents a platehavingitsinner surface provided with serrations; oritsinner surface may be provided with a groove, 6, or recess to fit overthe spoke, and a serrated portion, 0, at one end to clasp upon thefelly. It-is further provided with a slotted hole at the other end toallow for adjustment with the bars B andthe wheel. Two of these platesare at tached to the outer end of each bar B by a bolt-,f, passingthrough them and through the bar and fastened by a nut, g, and thus forma" pair of clamping-jaws.

H represents a clampingbar having boltholes at its ends for thereception of bolts 7L and 2'. Two of these. bars are attached to each.bar B, between'the plate E and the inner end of upon the felly when thetightener is to be used to draw the felli-es together, as shown in Fig.1'. The outer end of each bar B, between the clamping-jaws E,is providedwith a cushion, K, which may be of chamois skin, cloth, felt, rubber, orany other suitable material.

The operation of my invention is as follows: The apparatus is placedbetween two spokes of a wheel,- near the felly, with the cushioned endsof the bars bearing against the spokes. The clamping-jaws E are thenpressed closely against the two opposite sides of the folly and securedby tightening the nuts 1 on the boltsf. The bars H are then placed oneon each side of the folly and tire and secured by the bolts h and t andtheir fastening-nuts, the bolts 2' being passed through the outer endsofthe bars outside of the tire, or,'if it is intended to take up the playin the fellies, by drawing the follies together the bars H are placedone on each side of the clam ping-jaws E and secured by-tlieboltshand'i,andtheendsofthejaWsEthusheld firmly tothe felly bytightening the bolts. The fellies are tightened by turning the screw Ain one direction or the other. If they are to be drawn toward eachother, the screw is turned so as to screw both of the threads into theirrespective bars, and the spaces between the fellies and the tirearefilled by thin pieces of any-suitable material put in with lead,paint, or any cementing substance to hold them in place. This is to bedone evenly around the wheel, so

as not to throw the wheel out of shape. If

they are to be pushed outward away from each other and against the tire,the screw is turned in the opposite direction, so as to unscrew thethreads i'rom their respective bars,

make the ends ofthe fellies bear solidly against and the joints betweenthe ends of the fellics are filled by pieces of any suitable material toeach other.

The screw A may be turned by means of an ordinary wrench applied to thehead a, or the device shown in Fi 3 may be employed. This consists of alever, L, having its fulcrum on the screw A, and carrying a pawl, M,engaging with a ratchetwheel, P, carried by the head a, as shown in Fi3.

The advantages of myinvention are: it is cheap and simple inconstruction and is strong and durable. It can be used to tighten thet'ellies by either drawing or pushing. The cushions K prevent themarring of the painted surtace of the spokes and fellies, and theserrated clamping-jaws take hold of the wood of the i'ellies, so as notto injure the same. The fastening-bars 11 hold the apparatus securely inplace and prevent it from slipping in either direction. It can be usedby any one, and can he used to tighten a wheel in cases where there isnot time to have the tire reset, and can be used when a load is on awagon to save n11- loading' the same.

Having thus described my invention, Iclaiiu as new and desire to secureby Letters Patent 1. Afelly tightenerconsistingofaright-andleft-threadedscrew, two interually-threaded bars, two pairs of serrated clampingjaws, and two pairs of fastening or clamping bars, H, I
